I am trying to figure out how to create scrolling text across my 34x16 bicolor led display but cant seem to figure it out.

Here is the code I use to display an image across the entire display. How can I adapt to this. Most code i find is for single color small displays but for some reason trying to adapt this to my program things just get messed up.

Your code seems to write to 16 elements 40 bits of blue each. There's no text involved yet it seems and we don't know what that display of yours is capable or how your led are arranged. Please post some more details about your display if you want useful answers.

If you display can just display bitmaps, you're first going to need a font. Those can be found in the libraries of various other displays, but you need to know how that font needs to be arranged.

Also your monster block of spaghetti code isn't really good and maintainable programming style. You better look up some concepts like loop and array in your favourite programming book.

After this, it's time to write or adapt a library for your display, so that you can do easy things like mydisplay.write ("Hello", 1, 5). The functions of that library depends largely on what you need that code for.

Lastly, once you have some text displayed, you can extend the library to offer some scrollable text function. But until then, a you have some work to do.
